DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] As an embodiment of the present invention, Figures 1 to 6 As shown, a recycling and processing device for waste down products described in the present invention includes a working box 1, a feeding port 2 for down products to enter is provided on one side of the working box 1, a conveying structure for conveying down products is provided on the inner side of the working box 1, a tearing structure for tearing and crushing down products is provided on the inner side of the working box 1, a hot air device 3 for blowing hot air upwards to lift and dry the down is provided below the tearing structure, a down extraction port 4 connected to the working box 1 is provided above the tearing structure, a discharge port 6 is provided on one side of the bottom of the working box 1, and an electric-controlled door 7 is installed at the bottom of the discharge port 6.

[0032] When in use, the waste down products can be fed into the working box 1 through the feed port 2, and the waste down products fed into the working box 1 are moved to the conveying structure, and the waste down products are conveyed to the side of the tearing structure by the conveying structure. The operation of the tearing structure will first pull and tear the waste down products on the conveying structure horizontally, and when the pulled and torn waste down products move with the tearing structure, the tearing structure expands, thereby pulling and tearing the waste down products longitudinally, so as to ensure the splitting effect of the waste down products and reduce the damage to the down in the waste down products, thereby improving the down recovery rate; the hot air device 3 blows hot air to lift the down, and cooperates with the extraction port 4 to extract the lifted down; the electric control door 7 can be opened regularly to discharge the waste accumulated at the bottom of the working box 1.

[0033] In order to ensure the stability of conveying of the conveying structure, as an embodiment of the present invention, the conveying structure includes a first rotating rod 8 and a second rotating rod 9, the first rotating rod 8 is located directly above the second rotating rod 9, both ends of the first rotating rod 8 and the second rotating rod 9 pass through the working box 1 and are rotatably connected to the working box 1, the middle parts of the first rotating rod 8 and the second rotating rod 9 are both equipped with rotating rollers 10 corresponding to the feed port 2, and a plurality of groups of pointed rods 11 are distributed circumferentially on the rotating rollers 10; one end of the first rotating rod 8 is fixedly connected to the first transmission gear 12, and one end of the second rotating rod 9 is equipped with a first driven gear 13 meshing with the first transmission gear 12 for transmission.

[0034] When in use, the first transmission gear 12 and the first driven gear 13 are meshed and driven to ensure that the two sets of rotating rollers 10 rotate stably. The pointed rod 11 is inserted into the waste down products, which can have a certain decomposition effect on the waste down products and ensure the stability of the conveying structure in conveying the waste down products. At the same time, when the tearing structure tears the waste down products, the waste down products are prevented from being directly pulled out of the conveying structure, which affects the tearing work of the waste down products.

[0035] In order to ensure the tearing effect of the tearing structure on the waste down products, as an embodiment of the present invention, the tearing structure includes two groups of tearing conveyor belts arranged in a mirror-symmetrical manner in the horizontal direction. When the two groups of tearing conveyor belts are working, the down products output by the conveying structure are conveyed between the two groups of tearing conveyor belts. The tearing conveyor belts include two groups of horizontally arranged conveying rollers 14. The two ends of the conveying rollers 14 pass through the working box 1 and are rotatably connected to the working box 1. The two groups of conveying rollers 14 are driven by two groups of transmission belts 15. A slide bar 16 is connected between the two groups of transmission belts 15. An elastic expansion component is slidably installed on the slide bar 16. A guide structure for controlling the expansion state of the elastic expansion component is installed on the inner side of the working box 1; the two upper and lower adjacent groups of conveying rollers 14 are meshed and driven by a second transmission gear 18 and a second driven gear 19. The second transmission gear 18 is installed at one end of one of the groups of conveying rollers 14 located at the top, and the second driven gear 19 is located below the second transmission gear 18 and fixedly connected to one end of the conveying roller 14 located at the bottom.

[0036] When in use, the two sets of tearing conveyor belts quickly pull the waste down products sent out by the conveying structure horizontally, thereby performing horizontal tearing work; the waste down products that are torn horizontally move with the elastic expansion component, and the elastic expansion component cooperates with the movement of the guide plate component 17 to gradually expand, thereby pulling and tearing the waste down products longitudinally, thereby ensuring the tearing effect of the waste down products; and, the elastic expansion component will be squeezed and restored to a compressed state as the guide plate component 17 moves toward one side of the conveying structure, thereby facilitating the longitudinal pulling and tearing of the waste down products again.

[0037] In order to ensure the expansion effect of the elastic expansion component, as an embodiment of the present invention, the elastic expansion component includes a plurality of groups of sliders 20 slidably connected to the slide rod 16, rubber springs 21 are connected between adjacent sliders 20, and curved hooks 22 are connected above the sliders 20, and the curved hooks 22 are bent toward the transmission direction of the conveyor belt 15.

[0038] When in use, the elastic expansion component can stretch and expand by relying on the support slider 20 of the rubber spring 21, and thereby drive the hook 22 to longitudinally pull and tear the waste down products, thereby ensuring the treatment effect of the waste down products.

[0039] In order to facilitate the control of the state of the elastic expansion component, as an embodiment of the present invention, the guide structure includes guide plate assemblies 17 symmetrically arranged on both sides of the tearing structure, and the side surfaces of the two groups of guide plate assemblies 17 that are away from each other are fixedly connected to the inner wall of the working box 1 through support bolts 23; the guide plate assemblies 17 include a first semi-annular plate 24 and a second semi-annular plate 25 that are vertically arranged, an upper side plate 26 is connected between the upper edge of the first semi-annular plate 24 and the upper edge of the second semi-annular plate 25, and a lower side plate 27 is connected between the lower edge of the first semi-annular plate 24 and the lower edge of the second plate annular plate, and the spacing between the two groups of first semi-annular plates 24 is smaller than the spacing between the two groups of second semi-annular plates 25.

[0040] When in use, the elastic expansion component moves between the two groups of guide plate components 17. As the spacing between the two groups of guide plate components 17 changes, the elastic expansion component expands and contracts, thereby driving the hook 22 to move; wherein, when the elastic expansion component moves toward the side away from the conveying structure along with the tearing conveyor belt, the spacing between the two groups of guide plate components 17 gradually increases, and the elastic expansion component stretches, thereby driving the hook 22 to longitudinally pull and tear the waste down products; conversely, when the elastic expansion component moves toward the side close to the conveying structure along with the tearing conveyor belt, the spacing between the two groups of guide plate components 17 gradually decreases, and the elastic expansion component is compressed, thereby restoring the elastic expansion component to a compressed state, thereby facilitating the longitudinal pulling and tearing of the waste down products again; and as the elastic expansion component stretches, the torn waste down products on the hook 22 gradually detach, thereby facilitating the conveying of the torn down jacket to the side of the discharge port 6 and avoiding the accumulation of too many torn waste down products on the hook 22.

[0041] In order to ensure the operation of the hot air device 3, as an embodiment of the present invention, the hot air device 3 includes an air inlet plate 28 installed at the bottom of the working box 1, and a hot air fan 29 is provided below the air inlet plate 28. The hot air fan 29 blows hot air toward the tearing structure, and the hot air fan 29 is fixedly connected to the outer side of the working box 1 through a support frame 30.

[0042] When in use, the hot air blower 29 can blow up the down leaking out of the waste down products by tearing the tearing structure, thereby facilitating the extraction of the down through the extraction port 4; and the hot air blower 29 can also blow waste materials such as cloth used to wrap the down, thereby facilitating the waste materials to separate from the tearing structure and fall to the side of the discharge port 6, thereby facilitating subsequent transfer and processing.

[0043] In order to prevent waste down products from getting stuck on the pointed rod 11 and not being able to detach, as an embodiment of the present invention, a first curved plate 31 with an upward curved surface is provided below the first rotating rod 8, and a second curved plate 33 with an downward curved surface is provided above the second rotating rod 9. The first curved plate 31 and the second curved plate 33 are both provided with grooves 34 corresponding to the moving trajectory of the pointed rod 11. The upper parts of both sides of the first curved plate 31 are connected with first cross bars 35. The working box 1 is provided with vertical grooves 5 corresponding to the first cross bars 35. Both ends of the first cross bar 35 pass through the vertical grooves 5. A slide plate 37 is vertically slidably connected to the outer side of the working box 1, and the slide plate 37 is fixedly connected to one end of the first cross bar 35; the lower parts of both sides of the second curved plate 33 are connected with second cross bars 36, and the second cross bars 36 are fixedly connected to the inner wall of the working box 1.

[0044] When in use, the pointed rod 11 moves along the slot 34, and the waste down products on the pointed rod 11 will squeeze the first curved plate 31 or the second curved plate 33, so as to facilitate the waste down products to separate from the pointed rod 11 and ensure the stable transportation of the waste down products; at the same time, the first curved plate 31 can automatically rise when a large number of waste down products enter the conveying structure, so as to avoid the waste down products from being stuck between the two sets of rotating rollers 10.

[0045] In order to cope with the changes in the feeding amount of waste down products, as an embodiment of the present invention, a driving structure is installed on the outer side of the working box 1, and the driving structure is fixedly connected to the slide plate 37 on one side of the working box 1. The driving structure is respectively transmitted to the conveying structure and the tearing structure through the transmission structure.

[0046] When in use, the waste down products entering the conveying structure will squeeze and lift the first curved plate 31, and the more waste down products there are, the greater the lifting height of the first curved plate 31, and at this time the greater the lifting height of the slide rod 16, thereby adjusting the position of the driving structure; as the height of the driving structure changes, the greater the lifting distance of the driving structure, the lower the speed at which the conveying structure is driven to operate, and the higher the speed at which the tearing structure operates, thereby avoiding the conveying structure from conveying waste down products too quickly, which makes it difficult to ensure the processing quality of the waste down products.

[0047] In order to adjust the speed of the conveying structure and the tearing structure according to the feeding amount of the waste down products entering the conveying structure, as an embodiment of the present invention, the driving structure includes a support plate 38, the support plate 38 is fixedly connected to the slide plate 37, and a driving motor 39 is installed on the support plate 38. The output shaft of the driving motor 39 is vertically arranged, and the lower end of the output shaft is fixedly connected to a friction transmission wheel 40;

[0048] A first worm 41 and a second worm 42 are installed on one side of the working box 1 in parallel and inclined arrangement, and both ends of the first worm 41 and the second worm 42 are rotatably connected to a bracket 43, and the bracket 43 is fixedly connected to the outer side of the working box 1, and the lower end of the first worm 41 is coaxially connected to a first conical friction wheel 44 with a larger upper portion and a smaller lower portion, and the upper end of the second worm 42 is coaxially connected to a second conical friction wheel 45 with a smaller upper portion and a larger lower portion, and a vertical gap is formed between the first conical friction wheel 44 and the second conical friction wheel 45, and the friction transmission wheel 40 is located between the first conical friction wheel 44 and the second conical friction wheel 45 and frictionally transmits the first conical friction wheel 44 and the second conical friction wheel 45 respectively; one side of the first worm 41 is meshed with a first worm wheel 46, and the first worm wheel 46 is fixedly connected to one end of the first rotating rod 8, and one side of the second worm 42 is meshed with a second worm wheel 32, and the second worm wheel 32 is fixedly connected to one end of the conveying roller 14.

[0049] When in use, as the slide plate 37 drives the support plate 38 to move upward, the friction transmission wheel 40 simultaneously moves toward the larger end of the first conical friction wheel 44 and the smaller end of the second conical friction wheel 45, thereby reducing the speed of the conveying structure and increasing the speed of the tearing structure; conversely, when the slide plate 37 drives the support plate 38 to move downward, the friction transmission wheel 40 simultaneously moves toward the smaller end of the first conical friction wheel 44 and the larger end of the second conical friction wheel 45, thereby increasing the speed of the conveying structure and reducing the speed of the tearing structure.

[0050] A method for recycling waste down products, using the above-mentioned waste down product recycling and processing device, specifically comprises the following steps:

[0051] S1, putting waste down products into working box 1 through feed port 2;

[0052] S2, conveying the waste down products fed into the feed port 2 to the tearing structure through the conveying structure;

[0053] S3, the tearing structure tears the waste down products conveyed by the conveying structure;

[0054] S4, the hot air device 3 blows up the down and draws it out of the working box 1 through the down drawing port 4.

[0055] When the present invention is in use, waste down products can be fed into the working box 1 through the feed port 2, and the waste down products fed into the working box 1 can be moved to the conveying structure; the waste down products entering the conveying structure can drive the first arc plate 31 to move upward, and the first arc plate 31 drives the driving structure to move upward, thereby adjusting the transmission effect of the driving structure, the conveying structure, and the tearing structure, thereby adjusting the operating speed of the conveying structure and the tearing structure;

[0056] The conveying structure is meshed and driven by the first transmission gear 12 and the first driven gear 13 to ensure the stable rotation of the two groups of rotating rollers 10. The waste down products can be inserted into the pointed rod 11 to achieve a certain decomposition effect on the waste down products, and the stability of the conveying structure in conveying the waste down products can be ensured. At the same time, when the tearing structure tears the waste down products, the waste down products are prevented from being directly pulled out of the conveying structure, thereby affecting the tearing work of the waste down products.

[0057] The two sets of tearing conveyor belts of the tearing structure quickly pull the waste down products sent out by the conveying structure horizontally, thereby performing horizontal tearing work; the waste down products that are torn horizontally move with the elastic expansion component, and the elastic expansion component cooperates with the movement of the guide plate component 17 to gradually expand, thereby pulling and tearing the waste down products longitudinally, thereby ensuring the tearing effect of the waste down products; and, the elastic expansion component will be squeezed and restored to a compressed state as the guide plate component 17 moves toward one side of the conveying structure, thereby facilitating the longitudinal pulling and tearing of the waste down products again.

[0058] The hot air blower 29 can blow up the down leaking out of the torn waste down products, thereby facilitating the extraction of the down through the extraction port 4; and the hot air blower 29 can also blow waste materials such as cloth used to wrap the down, thereby facilitating the waste materials to separate from the torn structure and fall to one side of the discharge port 6, thereby facilitating subsequent transfer and processing.
